Abstract
To provide access to sequentially positioned printing machine operating stations (3, 14, 17, 33, 44) without having to tear a paper web threaded through the printing machine, in which the web passes, when in a printing position, essentially horizontally between the operating stations, a pair of vertically spaced substrate guide elements (23, 26; 123, 126; 56) are positioned on a vertical elevator positioning structure (22, 122; 52), the paper being guided between the guide elements, and the positioning structure permitting movement of the guide elements from an essentially central printing position to an upper position (23b) and a lower position (23a). The paper, before being passed between the substrate guide elements, is passed through a paper storage structure, for example by spaced, deflectable rollers which store paper in loop form, from which it can be released. The upper one of the guide elements is strong enough for an operator to stand thereon. When the guide elements are in their upper or lower position, respectively, an operator has access to the lower and upper operating elements of the respective adjacent operating station.
